Minecraft Version: 1.21.4
Minecraft Version ID: 1.21.4

That depends on the version of the game that this mod was designed for. It seems that the ModBlocks class is not registering the Mod Blocks correctly. This workflow is something that has changed in between 1.21 and 1.21.4 .

Can I do anything instead of waiting for the mod creator to update it to 1.21.4?

Generally the answer is no; but if you want to learn modding; I'd recommend watching Youtube Videos on the subject. My favorite for this is Modding by Kapuan Joe, but there are others. He goes over this very thing updating his 'ModBlocks' from his Example Mod to 1.21.3+, among other things if you really want to learn.
